IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent No. 52,797, dated February20, 1866.

To all whom it may concern:

Be it known that I, EDWARD STOCKER, of Lancaster, in the county ofLancaster and State of Pennsylvania, have invented a new and ImprovedMode of Constructing Stop- Cocks for Hydrants; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanyin g drawings, making a part of thisspecitication, in which- Figure l shows the casing of the hydrant,portions being removed to exhibit the cock, pipe, rod, 85o., in theinterior, T the top, U the bottom, of the case 5 Fig. 2, the stop-cockand pipes, drawn to the full size for an ordinary hydrant, detached inpart; Fig. 3, an extra key.

The nature of my invention consists in providing a stop-cock soconstructed that it can be taken out, repaired, and replaced without thedisagreeablelabor, when the ordinary cocks now in use are employed, ofdigging up the stock or casing, which (ligging up, being a dirty andexpensive job, often injures the stock and pavements, in addition to thetime and labor.

To accomplish this object I make my cock in two parts. Fig. 2 so clearlyshows these parts as to enable any one skilled in the business to makethe same.

The curved cylinder A is provided with screw ends E D, the key ot' thestop-cock being vertical, (shown by the dotted lines at A,) the squaretop B for the ordinary rod, and key R S for turning the water off orthrough the discharge-pipe K and external spout M. The square cone O,being ofequal height to that of the conic key-top B, is in like manneradapted to the turning-key R S, and by it operated and screwed onto oroft' from the lower portion, F G, which latter is iixed by a plate, N,to the bottom of the hydrant. The end Ghas a female screw, into whichthe supply-pipe I is screwed. There is also a key, H, (shown on thislower portion,) for the purpose of shutting off the supply of water inthe hydrant instead at some other remote point, often very inconvenientto do.

The extra key, Fig. 3, is for the purpose of fitting upon the top of thekey-rod R S in place of the lever-key O, Fig. l, to lengthen the samefor operating the 'long rod for unscrewing or shutting oft the waterbelow.

The discharge-pipe K has a short curved neck, provided with ascrew-thread at its upper end, into which the vertical pipe K enters, asalso the nozzle or spout M, from the outside of the case. This casingreq uires to be of such a width or clear spa-ce as to allow the upperportion ot' the cock to revolve freely on the screw end E, being, say,three and one-half inches, requiring an area of seven and onehalf inchesdiameter to turn in.

To remove the cock from the hydrant it is only necessary to unscrew thespout M and' shift the rod and key from B to C, and turning the samewill unscrew the cock and pipe A K. It is understood that the pipe maybe made to incline inward, so that the external end ofthe curve L willbe in a perpendicular line withthe outside of the curve at D, in orderto revolve with the stop-cock while unscrewing, when the minimumdiameter of the case is desired. Thus repairs are readily made and manyadvantages derived by this device.

The novelty consists in the arrangement ot' the parts and peculiarconstruction ot' the several conic key-points B H and turningpoint C, intheir combination, for the object stated. Otherwise the keys are of theor'dinary fashion, provided with a waste-opening, in the usual manner,in the cylinder.

The attachments ofthe discharge or supply pipe are not material to myinvention, and may be in the manner shown or otherwise, so as not toprevent the object in view-that is, the upper pipe, K', may becontinuous', with a short curved neck, L, in one piece, or the shortneck L, an independent screw-socket both for the vertical pipe K andspout M.

What I claim as my invention, and desire to secure by Letters Patent, is

The stop-cock A, with its curved screw ends E D and conic turn-points OB, in' combination with the fixed base F G N, with or Without thestop-oif key H, all arranged and operating substantially in the mannerand for the purpose specilied.

EDWARD STOOKEB.
